Clinical course and management of pancreatoblastoma in children.

Pancreatoblastoma is a rare malignant tumour. Two children with this tumour were managed in the last 2 years. Both presented with progressively increasing abdominal mass. The diagnosis was established only after laparotomy. In the first child, an 8 year old girl, the mass was arising from the body of the pancreas and only incomplete resection was feasible. She received postoperative chemotherapy and went into remission for a few months before presenting with jaundice and abdominal pain due to recurrent, metastatic disease in the liver and porta hepatitis. Further therapy was refused by the patient because of anorexia and social problems. The second patient, a 5-year-old girl, underwent distal pancreatectomy for complete removal of a large mass arising from the tail of the pancreas. Chemotherapy was begun postoperatively but discontinued by the patient. However, she has remained disease free 1 year after diagnosis. Histologic, histochemical and ultrastructural features of the tumour are detailed and the management discussed.
